FREDERICK JOSEPH FEIST, OF ROCHESTER, NEW YORK. ASSIGNOR, BY MESNE ASSIGN- MENTS, TO UNITED SHOE MACHINERY CORPORATION, OF EATER-SON, NEW JERSEY,

A CORPORATION OF NE JERSEY.

ROUNDING AND OHANNELING MACHINE.

Application filed September 9, 1916.

To all whom it may concern:

Be it known that I, FREDERICK J. FEIsT, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Rounding and Channeling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to machines for rounding, or rounding and channeling, the soles of shoes.

The invention is intended more especially as an improvement in the rounding and channeling machine shown and described in Patent No. 1,030,606, June 25, 1912, although it may be embodied in other machines. In the machine of the above patent the shoe is guided during the operation through the shank of the shoe by'a crease guide, and is guided during the operation about the forepart by a forepart guide, which is normally in raised or inactive position and which is moved into and out of active position by the operator in passing from the shank to the forepart or from the forepart to the shank. The crease guide is carried on the forward end of the crease guide lever and is positioned during the operation through the shank by devices on the forepart guide lever which engage the crease guide lever between its fulcrum and the crease guide at a point comparatively remote from the line of thrust on the crease guide. Under some conditions, therefore, the upward pressure of the shoe against the crease guide is liable to spring the crease guide lever upward out of proper position, or to cause an improper relative movement between the crease guide and the forepart guide in passing from the shank to the forepart or from the forepart to the shank, particularly in operating upon shoes in which there is less projection of the sole about the forepart than through theshank.

It is accordingly one object of the invention to-provide novel and improved means for rigidly supporting the crease guide against the pressure of the shoe while the Specification of Letters Patent.

forepart guide is out of action. To this end one feature of the invention contemplates the provision of an abutment arranged to overlie and support the crease guide or front end of the crease guide lever while the f0repart guide is out of action and to move out of active position when the forepart guide is moved into action, so that the crease guide may move with the forepart guide during the operation about the forepart. The abut ment may cooperate with a cam surface on the crease guide lever to allow the crease guide to gradually rise as the forepart guide is moved down into active position in case the forepart of the sole is to be trimmed closer than the shank.

It is desirable that the edge of the sole be trimmed at substantially right angles to its tread surface, and in case the curvature of the surface at the sole edge is substantially different along the shank and forepart, the angle or tip of the shoe should be changed .in passing from the shank to the forepart and from the forepart to the shank. It is accordingly a further object of the invention to provide novel and improved means for thus tipping the shoe. To this end a feature of the invention contemplates the provision of means for varying the position of the sole rest which determines the angle of the sole with relation to the trimming knife in moving the forepart guide into and out of active position.

In addition to the features outlined above, the invention also includes certain further features of construction and combinations of parts which will be hereinafter described and referred to in the claims.

The invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

In the drawings Figure 1 is a right-hand side elevation showing so much of a rough rounding and channeling machine as is necessary to illustrate the application of the present invention thereto; and Fig. 2 is a.

partial front elevation on a larger scale.

In the drawings the invention is shown as embodied in the machine shown and described in the patent above referred to. The machine is provided with a reciprocating trimming knife 2, a channel knife 4 carried in a channel knife block 6, which also acts as a support for the sole at the operating point, a feed jaw 8, a crease guide 10, and a forepart guide 12. The forepo-rt guide is carried on the forward end of a forepart guide lever 14 secured to a rock shaft 16 and moved into and out of active position through a treadle rod 18, the upper end of which is connected to one arm of a rock lever 20, another arm of which is. connected by a link 22 with an arm 24 secured to the rock shaft 16, as more fully shown and described in the patent above referred to. The crease guide 10 is secured at the forward end of a crease guide lever 26 which is held in engagement with the devices which de: termine its vertical. position and control its vertical movements by a spring 28.

In the construction shown, the vertical position of the crease guide and crease guide lever during the operation upon the shank, or while the forepart guide isout of active position, is determined by an abutment in the form of an adjustable screw 30 arranged to overlie and be engaged by the horizontal arm 32 of a plate or clip 34 which is secured to the forward end of the crease guide lever. Theabutment screw is carried in the forward end of a horizontal bar 36 mounted to slide in a bracket'secured to the frame of the machine and having its rear end arranged to engage the arm 24. The bar is held in retracted position by a spring 38. As shown, the upper surface of the arm 32 which engages the abutment screw is inclined to form a cam surface for causing the crease guide to gradually rise as the forepart guide is moved into action, and to gradually move downward as the forepart guide moves out of action.

When the forepart guide is moved into action by depressing the treadle rod 18, the arm 24 swings forward and advances the bar 36 so that the abutment screw 30 moves forward over the arm 32 and into position in front of the arm where it will not interfere with the vertical movements of the crease guide with the forepart guide during the operation upon the forepart. As the abutment screw moves forward over the arm 32, the crease guide gradually rises 1111-.

til the stop screw 40. on the foreport guide lever engages the stop plate 42 on the crease guide lever, after which the vertical movements of the crease guide are controlled by the forepart guide. When the forepart guide is moved out of action, the arm 24 swings toward the right in Fig. 1, and the bar. 36 i retracted, moving the abutment screw 30 over the arm 32 so that the abutment screw will gradually depress the crease guide as the forepart guide moves out of action in passing from the forepart to the shank.

In the above construction the abutment for receiving the upward thrust on the crease guide supports the crease guide lever approximately in the line of thrust, so that the crease guide is held or locked rigidly in position while the forepart guide is out of action. The abutment also continues to rigidly support the crease guide and to, positively control the movement of the crease guide with relation to the forepart guide as the forepart guide is moved into and out of action and until the, forepart guide en.

gages the crease guide and positively controls its movements. The proper relative movements between the crease guide and forepart guidein passing from the shank to the forepart and from the forepart to the shank are therefore insured.

In addition to the sole supporting block 6 which engages. and supports the sole substantially at the point of operation, a second sole support 44 is provided for engage ing and supporting the sole and determining the angle at which the sole is presented to the rounding and channeling knives. As shown, this support is pivoted to the slide which carries. the channel knife block, and its position is determined by an adjustable. stop screw 46, the rear end of which engages a plate 48. The stop screw is held in engagement with the plate by a spring 50 connecting the sole support with the. knife block slide. The plate 48 is provided with a cam surface andis arranged to be moved vertically and thus vary the position of the sole support 44 and consequently the angle of the sole with relation to. the trimming knife. Asshown, the cam plate 48is formed 7 on the end of a lever 52 which is supported on a pivot screw 54 and is provided with a rearwardly projecting arm slotted to. embrace the treadle rod 18. Adjustable collars 56 are secured to the rod above and below the lever 52 in position to engage and rock the lever when the rod is lowered or raised to throw the forepart guide into and out of action.

When the forepart guide is out of action, the cam plate 48 is in its lowered position so that the sole support 44 is retracted and in position to properly support the sole during the operation through the shank. Then the treadle rod 18. is moved downward to throw the forepart guide into action, the lever 52 is rocked; and the'cam plate 48 raised to move the sole .support 44 forward.

part guide out of action, the lever 52; is rocked to lower the cam plate 48 so that the sole support 44: is retracted into position to properly support the sole during the opera-- tion through the shank. Thus the sole support 44. is moved, in throwing the forepart guide into and out of action, to vary the tip or angle of the sole with relation to the trimming knife, so that the edge may be trimmed at right angles to the surface of the shoe solo in operating upon shoes in which the edge of the sole has a greater curvature around the forepart than through the shank. By properly adjusting the collars 56 the vertical movement of the plate 48 may be varied in accordance with the variation in the curvature of the sole edge along the shank and forepart. By adjusting the screw 46, the position of the sole support during the operation through the shank and through the forepart may be varied. In case the angle of the sole with relation to the channel knife is not to be changed in passing from the shank to the forepart and from the forepart to the shank, the cam 48 may be disconnected from the forepart guide operating mechanism, or may be removed, and the position of the sole support 44 in such case may be determined by the engagement of the adjusting screw 46 with the cam or with the front of the carrier slide on which the sole supporting knife block 6 is mounted.

While it is preferred to employ the specific construction and arrangement of parts shown and described in embodying the invention in the machine of the patent above referred to, it will be understood that this construction and arrangement is not essen tial to the broader features of the invention, and may be varied or modified as found desirable or best suited to the construction of the machine in which it is to be embodied.
